76 A with NB 220

76 A with NB 220

Thermal overfill prevention device, fulfilling the requirements of the German Water Resources Act (WHG)

Easy to use and reliable

The ideal solution to overfill prevention of tanks for water polluting liquids. With its easy installation and the option of acoustic or optical sensors, the overfill prevention has proven its reliability for years.

Level Detector 76

The Level Detector 76 from FAFNIR can be used in any container (outside the Ex-zone) where you require an overfill prevention or a limit switch. Whether it is a tank with a volume of several thousand litres or a containers with a smaller volume, we have the appropriate overfill prevention device.

76 A

Our standard device for all applications, easy to install with a reverse polarity protected cable

76 C

With a permanently installed cable, for applications where there is no space for the enclosure, or for OEM applications with a pre-configured cable.

76 N

All parts exposed to liquid are manufactured from stainless steel 316L. The enclosure is nickel plated; this means the sensor is suitable, for example, for AdBlue.

Transducer NB 220

Installing this stand-alone device is very easy. We have the right solution for you, whether as a simple relay output for the connection of PLC (NB220 H), as a stand-alone solution with an additional integrated optical and acoustical alarm (NB 220 QS and NB 220 QSF), or even with switched 230 V to directly connect an electrical consumer i.e. a pump (NB 220 QS).
